Namanny, RR. 2,Denison, Iowa Filed June 8, 1959, Ser. No. 818,816 1 Claim. c1. 1-49This invention relates to tools and more particularly to a staple setterand hammer especially useful in applying fence wire to fence posts orthe like.

An object of the invention is to provide a hammer capable of maintaininga supply of staples within the handle thereof, the staples beingautomatically fed in response to reciprocation of the hammer into adischarge chamber after which they are set into the wooden posts fordriving.

Another object of the invention is to provide a tool for materiallyreducing the time and eifort involved in stringing fence wire or otheranalogous jobs, the tool containing a magazine supporting staples thatare yieldingly pressed toward a staple receiving chamber in the head ofthe hammer. The chamber has a cavity and a weight which isreciprocatably mounted in the chamber so that upon normal swingingmovement of the hammer the weight drives one staple into the fence post,at least starting the staple or setting it so that it may be completelydriven in. This always leaves one hand of the user of the tool free tohold the wire or to do any other job.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter escribed and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a top view of the hammer showing it in use, portions of thehammer handle being shown in section to illustrate otherwise hiddendetails of construction.

Figure 2 is a longitudinal sectional view of the hammer and taken on theline 22 of Figure 1.

Figure 3 is a sectional view on an enlarged scale and taken on the line3-3 of Figure 1.

Figure 4 is a sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a sectional view taken on the line 5-5 of Figure 2.

Figure 6 is a sectional view taken on the line 66 of Figure 2.

Figure 7 is a sectional view taken on the line 7-7 of Figure 2.

Figure 8 is a perspective view of the staple advancing pusher mounted inthe magazine for advancing the staples.

In the accompanying drawings, there is illustrated a conventional fencepost 10 and a conventional fence wire 12. The post and wire areillustrated to show one possible use of the hammer 14, although it isevident that other uses are quite obvious. Hammer 14 has a hollow hammerhandle 16 and a hollow head 18. The handle has a pair of side walls 26and 22 (Figure 7) provided with longitudinal grooves 24 and 26 extendinglengthwise of the handle. These grooves receive the lateral pins 28(Figure 8) on opposite sides of the members 30 and 32 of thefollower-type staple advancing device 34. An inverted substantiallyU-shaped member 36 embodies limbs secured to cooperating ends of sidemembers 30 and 32, and a pair of thrust or reaction plates 38 and 40 aresecured to the opposite ends of members 36 and 32. Expansible coilsprings 42 and 44 are engaged with thrust plates 38 and 40 and with afixed closure 46 at one end of the hammer handle. The closure is held inplace by screws 48, which may be threaded in place or otherwise secured;and member 36 operates on guide 104.

Device 34 is slidingly operable in the magazine 50 defined by the sidewalls of the hollow hammer handle. This magazine contains a quantity ofstaples 52 which are pushed forward toward the hammer head 18 at alltimes by the yielding bias of springs 42 and 44. A door 56 connected byhinge 58 to the top wall of the hammer handle, may be opened to load themagazine 50 with staples. The door may have a small catch thereon tohold it in place and preferably has a small fingergrip 60 for hingedlylifting the door to the open position.

Hammer head 18 is made of a hollow body or tubular guide 62 having fourside walls 63, 64, 65 and 66. There are parallel grooves 68 and 76) inwalls 65 and 66 and these receiving lateral projections 72 and 74 onopposite sides of the weight 76. The weight is mounted in the chamberdefined by the side walls 63, 64, 65 and 66 of the hammer head. One endof chamber 80 is closed by the hammer head striker 82 that has a reducedshank portion 84 disposed in chamber 80. Striking member 82 is held inplace by screws 86 or by like fasteners or may be made fixed in someother Way to the remainder of the hammer head.

There is a staple receiving chamber 90 in the hammer head for receivingstaples 52 when they are pushed thereinto by the bias of springs 42 and44. Further, the weight 76 has a notch 92 between its upper and lowerends to form a pocket within which to receive each staple. This notch isseen in the side view (Figure 2) and there is one staple in the pocket.The lower end of chamber 90 has an opening 96 for the discharge of thestaples. A pair of aligning bowed leaf springs 100 and 102 are attachedto the sides 65 and 66 and grip the sides of the staples lightly toretain them in proper position for starting the staples, for instance asshown in Figure 5.

In use and operation its i assumed that the magazine 56 contains aquantity of staples 52 and that the staple advancing device 34 is inplace. The hammer is swung in a normal arc and this causes the weight 76to move down. The weight may move down only a predetermined amountinasmuch as grooves 76 and 68 that accommodate the projections 72 and 74have ends which terminate adjacent to springs and 162 (Figure 3). As theweight moves down the staple in pocket 92 also moves down. Thispositions the first staple as shown in dotted lines in Figure 3.

Upon a subsequent swing of the hammer, the staple that is held inposition by springs 100 and 102 is started in a fence post 10 and at thesame time another staple is received in the pocket 92 for subsequentoperation.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

A fence wire staple setting, starting and driving imple ment comprising,in combination, a hammer embodying an elongated hollow handle havingtop, bottom and side walls defining a staple magazine, said handle beingopen at its outer distal end and communicatively joined to anintermediate portion of a right angularly disposed tubular guide, aportion of the top wall of the handle adjacent said tubular guide havinga staple loading opening, a door there-for, an elongated centrallypositioned rib fixed in the hollow portion of said handle and of alength generally commensurate with the length of the handle and having across-section corresponding to the shape of a conventional U-shapedfence wire staple, said rib serving to permit a plurality of staples tobe slidingly saddled thereon in a manner that the staples may be ejectedthrough the open outer end of the handle into said tubular guide one ata time, a follower-type staple ejector comprising a U-shaped member alsostraddling the rib engageable with staples strung on said rib, a pair ofspaced parallel limbs keyed in grooves provided therefor in side wallsof said handle and having forward ends connected to intermediateportions of the arms of the U-shaped member, said limbs being disposedand extending along the longitudinal sides of the rib, coil springsinterposed between rearward ends of the limbs and the inner end of saidhollow handle, weight means slidingly keyed in the hollow portion ofsaid guide, said weight means having a staple receiving and deliveringpocket, one end of said guide being open to discharge the staples, andthe interior of the guide adjacent said open end having opposedlongitudinally bowed spaced parallel staple supporting springs.
